• 50mm diameter x 40mm thick.
• Quantity: 1
• Grade: N45
• Poles: Flat faces.
• DANGER!!! See warnings below.
• Pull: Specs say it needs 130kg to pull this magnet directly off 8mm steel plate and a hand cannot do this! It needs to be mounted! Resistance to sliding is about 1/3 of that figure.
• About 10 times more pull than a traditional ferrite-type magnet.
• Neodymium magnets never weaken with age
• Triple plated for durability: Ni/Cu/Ni
• Note: The shipping cost reflects the packaging required.

• I use one mounted in a handle, along with large steel balls, to remove dents from saxophones.
• I cannot think of any valid domestic use. Too dangerous.

• See Product Details!
• This, and another magnet or steel object, can accelerate uncontrollably towards each other and collide at enormous speed, behaving like a sledge hammer, crushing any flesh or small bones in the way, possibly shattering the magnet, and shooting out sharp fragments. Eye protection needed!
